sourdough waffles

I’ve always liked waffles. Who doesn’t!?

Then I traveled to Belgium and figured I’d reached waffle heaven. Once you’ve had crispy, chewy, yeasty Belgian waffles there’s no going back. I thought Belgian waffles were the pinnacle of waffle perfection.

But I was still willing to try another kind of waffles.  I wanted to use some of my sourdough starter, but didn’t feel like making bread.  I love the health benefits of sourdough, so I figured I’d try a sourdough waffle and see how I liked it.  How could I not like waffles?

Little did I know I was about to step into the best waffle eating experience of my life!

Why It’s A Smart Choice

Health Benefits

This article has a great summary on the health benefits of sourdough bread.  Check it out for all the references but here’s the TLDR version:

  • The lactic acid bacteria cultured from sourdough starter breaks down most of the gluten in wheat flour. Although it’s still not recommended for people with Celiac to run out and buy sourdough bread, this is a promising area of research for Celiacs. This is good news for people with gluten intolerance, who may be able to handle a small amount of gluten.
  • The probiotics (good bacteria) in sourdough are able to survive the heat from the baking process! These bacteria make their way to the gut where they promote a healthy immune system.
  • The sourdough bacteria are able to breakdown phytic acid found in whole grains. Phytic acid binds to minerals, rendering them useless for absorption by the body. So sourdough bread gives us more minerals to absorb such as iron, magnesium, and zinc!
  • Acrylamide, a carcinogenic compound, is formed when the amino acid asparagine is dry heated with other nutrients. This happens in the crust of bread or when bread is toasted. Sourdough bacteria reduce the amount of asparagine, thus reducing acrylamide production!
  • Sourdough bread has the lowest effect on raising blood sugar. In this study, subjects who ate sourdough bread for breakfast saw improved blood sugar control after lunch and even hours after lunch!

  1. I love sourdough too! I got into it when off on mat leave with my first. This post has got me inspired to start again. My new starter is hopefully brewing yeast on top of the fridge right now! I also loved to make sourdough crackers for my little one. So easy and I felt good about her eating them!

    1. Sourdough is so delicious! So far I’ve made basic bread, crepes, and a seed bread (recipes to come!). I thought about the idea of crackers. Would you mind sharing your recipe?

  2. These sound amazing.

    Jessica do you think it would work with Rice Flour? I’ll try it if you think it might.

    1. They are amazing! I haven’t made them with rice flour and can’t be confident of the switch. Corinna has made them with her GF sourdough starter so she would be the one to go ask!

  3. Just made my second batch of these! I plan on freezing them and popping them in the toaster for a quick and tasty breakfast. I’m so glad you shared this recipe as it is tasty, easy and good for you too! I think this will become a family staple.

  4. making my first batch of starter and can’t wait to make waffles! What kind of waffle maker do you have? I love the mini size!

    1. Sourdough is so rewarding! You’ll love it 🙂 I have a 4-waffle capacity waffle maker and I love it! I think it’s a Breville. Dear friends gave it to us for our wedding ( a few years ago now).

  5. I was always taught to never overstir pancakes or waffles and one they’re mixed to leave them alone. Just thinking of adding the eggs and baking soda after they’ve been sitting puts me in a panic . Do I literally just stir it in?

  6. Can these be made without eggs? Our granddaughter is allergic to eggs so we are looking for recipes that she can eat.

  7. Made these this morning and they are by far the BEST waffles I have ever eaten. I did not alter the recipe at all and they turned out perfect. Thanks for sharing such a fantastic recipe.

  8. These are so good! I make them at least twice a month and always try to double the recipe (and freeze for toasting). I have made them with flaxseed instead of egg, soy milk, and coconut oil instead of butter for a vegan option. They still turn out really good! (But not as good).

  9. Just made this recipe for the second time this morning. It is so easy and delicious. This time I substituted 100%whole wheat pastry flour and sprinkled in a few dried.cranberries for a special treat. They were amazing. Thanks so much for sharing this recipe!

    1. Not familiar with it. I have a new recipe plug-in on my site. With my old one there was a spot to fill in for where you adapted a recipe from but now that info was lost in the migration process!

    1. Good question! I posted this recipe when I was more of a sourdough newbie! I’ve updated the post, it uses FED starter!

  10. Hello! I’m new to the sourdough world and just fed my starter for the first time a few hours ago. Would it be ok to take a cup out to prepare your recipe or should I wait until tomorrow evening to begin? Thanks in advance!!

    1. Did you get an established starter from someone else or is this just day one of a brand new starter?

  11. I’ve made these several times and we love them, but I’ve always used my unfed discard starter and they come out great and are so delicious!
